Question

A wire is looped in the form of a circle of radius 28 cm. It is re-bent into a square form. Determine the length of the side of the square.

Answer 1

We have,
Length of the wire = Circumference of the circle

Length of the wire = ` 2 × \frac { 22 }{ 7 } × 28 cm [`

Length of the wire = 176 cm ….(i)

Let the side of the square be x cm. Then,

Perimeter of the square = Length of the wire

⇒ 4x = 176 [Using (i)]

⇒ x = 44 cm

Hence, the length of the sides of the square is 44 cm.
